摘　　要：综述了近年来国内外高温环境下在用压力容器缺陷检测技术、高温材料数据库及其安全评估方法的发展状况 ,内容分为检测技术及材料数据库和评估方法两部分。本部分介绍了世界上现有的高温环境下含缺陷结构完整性评定方法和规范 ,包括 :美国ASMECCN -47案例 ,英国的R5、BS791 0规范 ,法国的A1 6,德国的双判据方法以及最近发展起来的与时间相关的失效评定图法 (TD FAD) ,比较了其优缺点 。In this work, a review is made on the state-of-the-arts of non-destructive measuring technique, materials database and safety assessment technology for high temperature pressure vessels. According to its content, it was divided into two parts: measuring technique and materials databank and assessment technology. In this part, some procedures and approaches for integrity assessment of defected structure operating at high-temperature are introduced, including American ASME CC N-47, the British Energy R5 and BS7910, the French A16 and the German two-criteria method, and the time dependent failure assessment diagram approach etc. Their advantages and shortcomings are compared one by one. Then further research efforts needed in China are also suggested.
